Astrum: This Will Be My Most Disliked Video On YouTube.

Will it, Alex? …Well I love it.

But I had the good fortune to be trained in physics and chemistry. So few people are. It follows that most of your audience are going to rate it like they rate their football team, or fav pop group.

Astrum examines the data on past global temperatures. How can we reasonably say what global temperatures were in the deep past? Astrum explains how – with video clips that fit the narrative, and aren’t just atmospheric wallpaper.

The video is most instructive on ice core studies. I learned a lot. And I like learning.

A lot of people don’t. They don’t like being jolted out of their misconceptions. It’s like being kicked out of their warm smelly bed and told to face the day.

Verdict (and maybe this is why Astrum anticipates a lot of dislikes): we have been warmer in the past.

But today’s rate of global temperature increase is exceptional: it is too fast for many species to adapt, especially highly evolved apex predators.

And that’s where the mischief lies.

Apex predators aren’t freeloaders, as I used to think – living off the fat of the land. They create and sustain the world we see. As is amply proven when they go extinct or are deliberately exterminated.

Tigers, for instance. They don’t actually get to eat all that much of the big game they kill. Most of it goes to feed the rest of the jungle.
